Hi Vegita,
You ask a good question - and reviewing prompts that you have previously gotten wrong (as well as those that you have correctly answered) is an important aspect of the overall GMAT training process. The broader issue is what exactly you are doing when you conduct this type of review. Depending on the type of Verbal questions you're reviewing, you might be focused on reviewing Grammar/Idiom rules or logical patterns in CR/RC or even why certain types of answer choices are incorrect. You should NOT be simply reviewing questions just to see whether you remember what the correct answer is or not; reviewing the 'process' of answering each question is what matters (re: how can you use the 'steps' needed to answer this one question so that you can correctly answer similar questions in the future). If you're clear on the process (and you can remember to use it again in the future whenever it applies), then it stands to reason that you can stop reviewing that particular question.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
